One of the most interesting concepts to be introduced in positive psychology is the notion of positivity (see Chapter 19). Dr Barbara Frederickson (2009)

claims that individuals should experience three times as many positive as negative emotions in order to thrive and be healthy. She calls this the positivity ratio.

a. To see how scales are constructed, go to www.positivityratio.com/single.php and complete Dr Frederickson’s measure. Can you see which items contribute to the positive and negative scores?

b. Check your reliability. After recording your scores, fill out the measure again the next day. Have your scores changed or are you consistent?
